Kelsey Hatcher, a 32-year-old mom of three was born with a rare uterine anomaly called uterus didelphys, or two uteruses. However, she was not diagnosed with the condition until last spring, when she discovered she was pregnant – in each uterus.
Hatcher said her husband almost didn’t believe her.
“He said: ‘You’re lying,’ I said: ‘No, I’m not,” Hatcher told NBC News.
Uterus didelphys affects about 0.3% of women. The abnormality forms in the female embryo very early in development, around eight weeks gestation, according to fertility researchers.
I was going to ask if other animals were capable of multiple simultaneous pregnancies, but then I figured I should probably just google it.
Interestingly I found that it has indeed happened to humans, but it confirms your idea, because in the latest documented example, the children were born at the same time.

All mammals that give birth in litters have one large and “lumpy/compartmentalized” uterus. Opossums (not mammals) for example have a forked reproductive tract which forks in the vaginal canal with two distinct “halves” leading to a different uterine compartment. I don’t think there’s any animal with two completely separate uteruses; please correct me if there is one though 😛
Opossums are mammals, just not placental mammals. Marsupials are in the class of mammals, and kangaroos have two separate uteruses
True, and let’s also not leave out our fellow eggy mammals, the magnificent monotremes!
I mean this post is about one
